Migrated a Project to NWDI, Deployment aborted

Hi guys

I migrated an existing local Web Dynpro project to NWDI using this tutorial

[Migrating Local Web Dynpro Projects |http://help.sap.com/saphelp_nw70/helpdata/en/9e/1c200ac164cf4a942f2dacdf3359e9/frameset.htm]

I can build the project via "Development Component -> Build". It doesn't throws any errors. The building function is working fine.

BUT, if I try to deploy the project by using "Development Component->Deploy" it throws the error "Deployment aborted"!

The error message doesn't help me a lot

Aborted: development component 'myMigratedApp'/'my.biz'/'LOKAL'/'0.2010.09.15.10.09.42'/'0':Caught exception during application deployment from SAP J2EE Engine's deploy service:java.rmi.RemoteException: Cannot deploy application my.biz/'myMigratedApp.. Reason: Clusterwide exception: Failed to deploy application my.biz/'myMigratedApp. Check causing exception for details (trace file).

Hint: Are all referenced components deployed and available on the engine? (message ID: com.sap.sdm.serverext.servertype.inqmy.extern.EngineApplOnlineDeployerImpl.performAction(DeploymentActionTypes).REMEXC)

Deployment exception : The deployment of at least one item aborted

Any ideas how I can fix this problem?

Thanks
